Tom's Guide to Water Cooling
Aaron Cherrington writes "Tom's Hardware Guide has a pretty impressive rundown on how to setup a fairly sophisticated water-cooling system for your ever-growing heat problem in your proc/foundry. The guide even includes a movie! Funny how computers are beginning to develop like the early automobile industry."
I understand the need to be on the cutting edge of technology, and to puch your hardware right to the edge of the envelope... But isn't a water cooling system in a PC going just a *little* overboard for that extra 5% performance boost? Especially today when 2ghz processors are the norm. How fast does it really need to be?
But hey, to each his own. Or her own, I suppose.

That's why it's preferable to use distilled water, a very poor conductor.

Um, dude, in case you haven't noticed, computers have been around since the mid-1940s.

for the time and effort spent on this -- get some flourinert and just full-submerge your PC. a gallon is ~500 bux, cheaper if you buy more. Or hook up with somebody with access to some and buy used liquid for cheap ;-) -- it's used in all sorts of high precision equipment(s)

Since someone is going to say something about running water through your system and how you don't trust it, etc. etc. etc.. There are alternatives out there such as flourinert that have similar thermal properties but don't carry charges well. More expensive then water + wetting solution, but gives MUCH more peace of mind if you happen to be a paranoid person. Here's a link to an OC forum with a story or two on how the product behaves as well. A better article on watercooling (to the insane extreme) can be found here.

Let's take watercooling as an example. Heating water breaks the molecules apart. This is OK (up to a point) for pure water, but nobody actually uses pure water. Instead we use tap water, full of lead, acidophilus and other harmful toxins. When the heat from the overclocked PC causes those toxins to be released into the air--whoa nellie, we have ourselves an EPA Superfund site in a bottle.
Of course, anybody who's even slightly concerned about the environment knows all the above already. The trouble is self-centered morons like this guy who think the rules don't apply to him or that "just one more overclocked PC won't hurt anything". So please, Slashdot, quit glorifying this destructive pasttime and instead advocate the right solution: a new PC every six months.
Great. I guess we'll all be anxiously awaiting the arrival of Ralph Nader's new book, Uncoolable at Any Clock Speed.

Why do people even submit the stories? The Slashdot editors will probably post them anyways. Not to critize TH; it just seems that whenever they post a new article, it shows up a few hours later on the Slashdot front page. Maybe Slashdot needs a special "Tom's Hardware" topic or even it's own section (th.slashdot.org).
good guide on hardware for watercooling, but the video has the most atrocious trance as the background music that's been heard since 1999!

flourinert can build up static charges running through the tubing; and whet the charges get high enough, ZAP and there is a hole in your tube. (yes i speak from experience)
now, if you say "oh well at least it does not conduct electricity / short out my board" -- well, there is two problems with that: 1) thermally, your CPU will die, fast. 2) flourinert is damn expensive (~500 US / gal last i checked) -- having it leaking out of a hole onto the floor is not a good idea; 3) it is environmentally hazardous -- not that you might care -- but i'd figue i would mention it instead of having people wonder why there are locallized holes in the ozone layer above their neighborhood.

Another solution is to blow cool air over the hot parts, cooling them naturally and safely. No, you don't need to use the computer in a wind tunnel, just several fans / cold air guns / natives waving bannana leaves.

Seems to offset the actual value / use of having a system that runs 50 mhz faster.
After the tubing has been installed and the cooling circuit has been closed, turn the pump on, then pour the distilled water into the header tank until the entire system is filled with water. In order to break the surface tension of the water and prevent air bubbles from forming, add a drop of dishwashing liquid.
original page
I can think of something better to use than dishwashing liquid. Red Line Oil makes something called Water Wetter which does the same thing; Its primary function is to lessen water's surface tension in cooling systems in cars. From Red Line's webpage on the product (with advantages relating only to vehicles removed):
BENEFIT SUMMARY
You can get a bottle of this, put a little bit in with your tiny computer cooling system, the rest in your car's, and you'll have better cooling all around. And this stuff prevents foaming, rather than promoting it like dishwasher liquid.
look a bit lower on the page for the non-pro free version. it took me a sec too, but found it.
Sometimes you gotta be careful with this cooling business. Had a friend who hooked up a peltier to his computer, but got it *too cold*, and ended up condensating on his board and corroded all his little sensistive surface mount components! I keep asking him why he does it, I think it's an addiction or something. He never did anything past seeing how many thousands of frames per second he could get in Quake.

It depends on how you define, "out of control." Today's machines throw off tons of heat, and conventional coolers use a fight fire with fire method, expending power in the case to move fan blades ever faster to remove heat. A PC these days usually has 4 fans in it, more if you cool your hard drives, or want to double up. Water Cooling is an order of magnitude better at heat removal for the power consumed, and doing it quietly. And while about 6 months to a year ago it was a crude, voodoo art, companies are producing high end products that make it viable. It is a meer matter of time before the products start trickling down into cheaper less effective price ranges for those who want to just cool their processor, graphics card, etc, with a water based system. There are many sites that will allow you to do it on the cheap, and if youre building a system, and opt to use water instead of the conventional fans, you wont be spending much more money and youll have a quieter system. So, as you see, this isnt a matter of necessary, this is a matter of a better way to cool. I think in a few years, this stuff could be used in OEM PC's.

It's rather ironic that IBM and other large systems makers have spent millions of $$ to get rid of water cooling in their systems. The good old water-cooled TCM (Thermal Conduction Module) of IBM's 1990 mainframes was a very impressive piece of mechanical and thermal engineering. If you worry about the heat generated by a single CPU, imaging what it was like to cool one of these babies.
TCMs included spring-loaded copper pistons to maintain good thermal contacts on the chips. The thing was a plumber's nightmare. I remember an IBM field engineer who had to improvise a pipe soldering the night before a computer show because 1) there was no water cooling at the stands (geez, what an oversight), 2) IBM had to require a fire permit to let the plumber light a soldering torch, 3) by the time the fire permit came in, the unionized plumber was home while the on-salary, no-family-life engineer was getting ready for a looong night. Those were the days, when computers were freakin' huge and had to be watered like thirsty dinosaurs.
As a side note, the need for TCM was considered a nuisance. Customers released a collective sigh of relief when IBM dropped their fast but power-hungry bipolar technology in favor of cheaper, easier to cool CMOS chips. It's a shame that Intel's sloppy designs force an entire industry to go back to watering the dinos.

I can see it coming. Every 30,000 teraflops I'll have to haul the computer to Bendover's Quick-lube and have the coolant flushed or the warranty will be void.
Definitely loss of points at the end there. He "tipped his hand" in the lingo. Granted, there are many slashbots who think nothing of buying a new PC every 6 months and wouldn't even notice this, but most people would recognize this as "hyperbole"--a sure sign of a troll.
On the other hand, the results speak for themselves.
It's rare that you're presented with a knob whose only two positions are Make History and Flee Your Glorious Destiny.
Koolance has been building this type of system for quite a while now. The parts are almost identical except Koolance incorporates the radiator at the top of the case with with 'blowhole' fans moving the air and a digital temperature readout. Their more recent designs are modified Antec/Chieftec/Alienware tower cases (you can even get them with a window... geez...). The original cases were somewhat more impressive as they incorporated a liquid-cooled power supply as well. One amusing 'coming soon' product on their website is a liquid-cooled 1U case. I keep imagining a whole rack of these units and one word springs to mind: waterfall.
Maybe I missed something, but this picture suggeste the heat of the processor is used to warm up the harddisk (or the other way around). Either way I think this is not what you want.
Still, it looks VERY cool.
Privacy is terrorism.
Its not Intel's "sloppy designs" which have caused water cooling to come back into style. Actually a big reason most people do it, such as myself, is because we get sick of the noise, which is not entirely the processor's fault. Its beautiful to have a PC that's like any other applience, you don't notice it unless you need to use it.
On the engineering front, every modern good performing processor needs cooling. The number of transisters per cubic cm is enormous and increasing, so we're getting bigger chips using more energy and thus producing more heat. This is where a new technology must come and replace it, just like CMOS did with bipolar. Circuit engineers only pay attention to heat during the design phase if its a criteria (which isn't so much on processors) and is mostly left to those in the fabrication stage to optimize and fix. Only in the last few years has any decent energy saving technology started to become popular and important to designers, but in essence until heat is a limitting factor designs will focus on higher performance through novel techniques and providing developers with better tools (instruction sets).

I'm probably wrong about this, but here goes...
That might work for about 30 seconds before it exploded. It would be very, very hard to charge the system first - pour gas into a header tank? You'd need some special high-pressure lines and a bit more structually sound attachment system than a couple of zip-ties. The gas, once it expanded from the heat, would blow apart the system long before it reached the radiator.
Every cloud has a silver lining (except for the mushroom shaped ones, which have a lining of Iridium & Strontium 90)
Actually you want distilled deionized water with some Water Wetter or something like that. Although it might be worth the added risk to be able to say you need to pick up some Evion for your computer.
If you are worried about water, then get some actual deionized H2O.
Won't carry charges even if you submerge the computer in it, as long as you don't dump salt or any other material that will ionize.

The watercooling looked pretty neat. However, I didn't see any benchmarks for how much faster you could overclock your CPU if you went the water route. Anyone have any links for overclocked P4s & AMDs comparing and contrasting water cooling vs tradional fan coolage?
I've always been nervous about the idea of mixing water and electricity...
Why? Water doesn't conduct electricity.
I read a lot of claims about it being a silent cooling solution, and yet the parts consist of a pump and a large fan attached to the radiator. Not to mention the already existing HD and power supply fan. These things aren't exactly quiet in my experience.
Then again, I'm guessing that because of the watercooling, airflow isn't of as much importance so it can be stored away in a closed compartment, with perhaps only the radiator sitting outside your window or something. It would be nice to see a hack which cooled the power supply too, though perhaps its not real wise to have water running through such a high voltage component.
I.O.U One Sig.
I prefer the Lesser B.C.T.P. Version 2 (or any later version, at my discretion).
The "Worst Case Scenario" would be having one that rusts. Gives a whole new reason for Lexan cases.
One simple problem with this: dust. All sorts of stuff flies around in the air, and as anyone who's left a system running for three months and opened it knows, it collects in the system. And any skin oils or other deposits left in the system might compromise the non-conductivity of the water.
There is a version without _any_ spyware.. at least, there was last time I bothered to check.
Has anyone out there overclocked and/or water-cooled a Mac? This article has got me interested to try it, but I'm pretty afraid I'll screw it up, especially since all the articles on it seem to be PC oriented. I was mostly interested in getting rid of the fan, so it'd be quieter, but the article mentioned successfully overclocking a pentium 4 to 3000 mhz (apparently 3100 is the limit), and that got me drooling. I wonder how much a g4 can be overclocked?

Does anybody take Physics anymore?
Alcohol is much better than water for cooling and has other nice properties (ie no bacteria or algae).
Yeah. Back in the day, my dad (true story) cooled his Model A hot rod with alcohol.
-=>Funk Master=-
Actually going back and back, the original cars were cooled with simply water, which then moved onto alcohol(not that type) :), but moving farther along we get into the ethylene glycol(still alcohol) with older cars(green stuff), and a newer type of antifreeze(orange stuff), is NOT the same as the old green stuff, chemicaly it is diffrent and mixing the two gets you something along the lines of a paste consistancy, that is if it doesn't cause your plastic rad to be eaten alive or disolve your aluminum engine block.
In anycase, the only draw back I can see using the green stuff is it might eat the tubes and pump, the orange stuff might work better since it's designed for aluminum and plastic(modern cars), and isopropyl alcohol will most definatly eat the plastic/rubberish tubes and micro pump your using.
And remeber the golden rule of auto-body and engine building. Do Not Mix STEEL and ALUMINUM together even with a fluid. The aluminum will break down into a powder called aluminum sulfate. And the steel will start to grow aluminum sulfate crystals. So watch the connectors, and watch what the cooling block is made from. And what is used inside the pump for parts.
Om, nomnomnom...

True, it's not just Intel's fault.
I am fully aware of the constant progression of power density within processors. It's a problem in PowerPC and graphical chipsets, too.
But Intel is in a unique position to tackle the PC cooling problem from a system-wide point of view. Consider this: Intel is one of the largest motherboard suppliers in the world. They sell chipsets, mobos and assemblies. And they never started designing a system-wide cooling solution, in spite of owning many of the critical parts (CPU, bridges, minority stake in DRAM makers). No other actor is in such a position to set standards. Not Dell, not Compaq, not AMD.
That's why I believe Intel's relunctance to tackle this problem is plaguing the whole industry.
Thanks for your answer,

I know, nobody actually grounds themselves with a static strap when putting together a PC. But in this movie they handle the CPU with about as much care as your car keys. Either they are lucky or did the video with a dead CPU. I try to use a little more care to prevent frying a new CPU and losing a few hundred bucks.
Anybody want a peanut?
Thank-you
Nice try, but no cigar. When the manufacturer specifies the amount of flow for a given "pressure head", they are telling you how much flow you will get when pushing the water a certain distance uphill. While it is true that your water goes in a circle, and thus not really uphill, the resistance from those skinny hoses, pipes, elbows, and other fittings will have (for a given flow rate) the same effect as some amount of pressure head.
If you could choose, you would choose piping that would have as little resistance to flow as possible. Less resistance to flow lets you use a smaller pump. A smaller pump generates less heat. And that would be that much less heat to remove from the case and dump in your room.
Really? Then you wouldn't be afraid when I dip a hairdryer into your bathtub?
Ok, I just watched the video. It was pretty interesting, although the Euro-trash music kinda gave me a headache...
Anyhoo, I noticed that some of the tubes were connected to the nipples with plastic zip-ties. Zip-ties!!! Are you guys INSANE?
Let's see: I spent ~$800 for the parts, hours of planning, and hours of time assembling the parts, but I'm gonna use 10-cent plastic zip-ties??!
What's wrong with these people??
2 words: HOSE CLAMPS. They're metal, and they are a hell of a lot more reliable than those little pieces of plastic you're using.
Sigh...
i would NOT sudjest that... the water is your bathtub is NOT jsut water... all the impuritites such as the soap and other bits that come in tab water make it conductive... the water used in water cooling systems is purified so it doesn't clog up or create builup in the pipes... the main problem with water cooling over air cooling is condensation which is easily solved bymost setups
unzip; strip; touch; finger; mount; fsck; more; yes; unmount; sleep
this is the main reason water is cooling is best... many new cpu's run MUCHJ hotter than ever before as transistors are crammed in there... personally here is what i do:
1. UNDERclock the cpu
2. run a cooling system on passive dissipation (no fan)
3. enjoy silent computing
4. mumble mumble
5. profit (ok im working onthis one... im considering starting a service where i go to people's houses and tune their computers... like for real cheap make it quite and a little faster)
unzip; strip; touch; finger; mount; fsck; more; yes; unmount; sleep
Much, much less.
In general, any RISC (Reduced Instruction Set Computing device, such as those in Mac and Sun boxen) CPU has fewer stages of logic between registers than a CISC (Complex ISC) CPU (such as x86's). Fewer stages of logic means a higher ratio of wire (metal) to logic gates (silicon) in any given path. Signal propagation delay time in modern semiconductor processes are dominated by wire delays -- silicon gate delays are almost negligible. Also, signal propagation delay time varies with temperature strongly in silicon, but weakly in metal. So temperature effects make a bigger difference to max clock rate on a CISC vs. a RISC. Said differently: there's a smaller window of min/max conditions (PVT = manufacturing Process, Voltage, and Temperature) under which the a RISC CPU will work as intended vs. a CISC CPU.
Note to zealots: this should not be construed as (or used for) taking sides in the inane Mac vs. PC vs. whatever thing. It's about CPU design philosophy and implementation.
The reason Intel (or AMD) sells a CPU as a '1.7GHz' model instead of as a more profitable '2.0GHz' model is that some path of logic between registers in the chip won't work at 2.0GHz under the warranted PVT conditions (for commercial products usually: published MIN-MAX process, +/- 5%, and 0-100 degrees C transistor junction temperature - with a case and built-in cooling that usually allow for -10 to 50 deg C ambient temperature). Cooling (or increasing the volatage -- you can't control the process after the chip is made), is more likely to improve a CISC path than a RISC path (because of the wire to silicon ratio).
So the manufacturer can more easily certify the RISC device for operation at higher clock rates. But that also leaves the user with less room to tinker around, should s/he/it be so inclined.
Sorry for the long post (I've been thinking about this sort of thing in a roundabout and thinly related way for quite some time). Your question fell right in front of my hypno-train.
everything in moderation
The reason why water is used is because of it's exceptional thermal characteristics. Water has a heat capacity (at atmospheric pressure) of roughtly 4.2 J/g K. It also has a relatively high heat of vaporization (2.26 kJ/kg) and a boiling point above your target operating temperature. It's cheap to replentish. You can easily obtain cheap pumps that are designed to pump it safely and quietly.
Some heat capacities of common substances for comparison:
methanol, 2.5 J/g K
ethanol, 2.4 J/g K
ethylene glycol (antifreeze), 2.4 J/g K
vegetable oil, 1.7 J/g K
mercury, 0.14 J/g K
air, 1.0 J/g K
Obviously, to make this all meaningful, you need to take into account the density of the fluid at the operating temperature and thermal conductivity into your calculations to translate it all into a volumetric flow rate. You also need to consider whether or not a phase change is to be involved (and if it is, how you're going to deal with the associated pressure). Many substances are unsuitable for safety & health reasons (methanol, ethanol, etc. are a fire hazard.... mercury and methanol are quite poisonous). When you get through looking it all over, water is often used because it works without all kinds of complications in the design of the system. Your main concern with water is making sure it doesn't leak onto your mobo. If you use a halothane refrigerant, you're probably going to have to deal with phase changes (thus requiring a noisy compressor) and you're going to have to make it leak-free anyway (or you'll be shelling out big $$$ to replace the expensive refrigerant you lose).
The off-the-shelf system that Tom's Hardware demoed is looks great... too bad I can't afford it! :P
No, that's why we need to bring back unregulated Chlorofluorocarbons! Bathe your box in "inert" high heat-capacity liquid!
CFCs were never popular for their heat capacities. They were popular because their boiling points were in the right range and because of their vaporization enthalpies.
Thanks for the long post. It was really helpful, if only to fund my inactivity (or keep my funds inactive--a good thing, to be sure!).

Using a refrigerant cooling system for a PC, like a modified air conditioner, tends to work pretty well.
The coolant is at a much lower temperature, so it takes longer for it to warm up to the point where your PC fries if the compressor fails.
Secondly, it can be used to lower the temperature even more.
Unfortunately, there is a very serious problem with it. The temperatures are below the dew point, and cause condensation. This will eventually short out/damage the boards.
I've though of one way around that problem though, what if you basically freeze dried the computer? You build a case that is airtight, and won't crush under a vacuum. Then pump out most of the air/moisture with a vacuum pump. Lastly, you fill the case with CO2 or something. You get rid of the moisture, and with it the condensation problem. Its also a whole lot cheaper than Flourinert. The only problems I can see are during the vacuum stage. I'm not sure if there would be any problems with the chips exploding or components leaking in a vacuum?
I might try that sometime and see if it would work. I think the biggest problem would be making the airtight case.
first google the link.
Lets see, what more advantages are there.
-Makes your car go faster.
-Makes your pc go faster.
-Is a perfect Glycol replacement....
-Prevents your pc from freezing.
Wait.. yes this is a replacement for glycol anti-freeze. I would not just add it to the water, no way to tell what this will do to your waterpump.
I think you watch too much tv at 4AM. Or you just made one small troll.
If it helps, I run ALL the big fans (cpu + 3 case) @ 7v instead of 12v in my PC tower which makes it quite a lot quieter - with no overheating problems. Not sure how hard this is with a MAC, if the fans are powered off molex connectors very easy. see http://www.procooling.com/articles/html/quiet_fans _-_power_control_met.shtml for details. (I'm in no way affiliated with the website). Bear in mind though that I live in England which is a cold country! If your machine room/office/whatever gets hot, I wouldn't bother.
Water Wetter is powerful stuff!
Once, I was talking to another engineer who told me about his discovery of this product. Apparently, a couple of german engineers were paying him a visit, and one had a bottle of this stuff.
There was a small pond (about 60 foot in diameter) beside his company's office that had a few ducks calmly swimming on the water. The german engineer poured half of the bottle in to the edge of the pond, and the surface tension broke across the entire surface. The ducks sunk into the pond and drowned before they had a chance to try to fly away!
I know this is hearsay, but I don't doubt this guy.
-- Len
pure distilled deionised water still contains ions and is therefore conductive to some extent. water exists as a mixture of molecular H2O, OH- and H+ ions in equilibrium. even pure H2O left to its own devices will generate OH- and H+ ions to return itself to equilibrium.
Aside from being one overworked ad for Innovatek (not the best kit, but Tom sure thinks so), Tom has no idea what he's talking about.
Distilled water isn't used because if it leaks it isn't gonna cause a short...cause it could. There's all kinds of conductive things on your motherboard and the like that like to dissolve in water. Distilled water is used so that you minimize the battery effect between the radiator and waterblock (assuming one is of AL and the other is CU) and to prevent corrosion as much as possible (tap water and the like has all kinds of things that will work away at the waterblock, radiator, and tubes). Most people using a closed loop watercooling system have pinkish water cause they put Watter Wetter in it, which reduces the surface tension.
The location of the radiator DOES NOT MATTER. It's much more important to have the radiator getting it's air from outside the case and ideally blows it back outside the case (with duction or something similar). Radiators are frequently put at the top of cases because it's the most convenient place to put them...they aren't in the way of anything when they're sitting above the PSU.
With regards to his putting the block on the CPU:
"You should not use silver paste because the copper contact plate is very flat. "
That has to be one of the most inane comments I've ever heard. You WANT to use the silver compound because it will actually TRANSFER HEAT. The Silicone stuff is ok if you're not planning on doing great cooling, but silver is much better. The flatness of the block doesn't matter AT ALL in the choice of thermal compound. Silver is still better at being a TIM than silicone even if the core has better contact with the block for the simple reason that there are still gaps, and the micronized silver in Arctic Silver easily fits in them (as it's designed to do)...and will provide better heat transfer than the white goop.
You don't put the tubes on AFTER you've put installed all the parts...you do it FIRST. Putting the tubes on AFTER you put your blocks on is a VERY good way to destroy your computer parts as you're putting uneven pressure on them, and sometimes a goodly amount of that.
You also put them on first so that you can BLEED THE SYSTEM OF AIR. If Tom thinks that dyes can reduce the amount of thermal capacity of water, what do you think AIR does. There's a reason we're using water here...it's tons better than air at transfering heat, heck, air is used as an insulator in windows. So putting AIR in your system is going to GREATLY reduce the cooling capacity of your system.
Then there's the price. You get to pay 200 USD for a minimal cooling solution "kit" that you could get with separate parts for 150...or cheaper. With a better waterblock, too. AND with HOSE CLAMPS! God, zip ties are such a bad idea.
You sir are an idiot.
And that's about all this post warrants. Except maybe a question of who the hell modded you up???
Sheesh! "heating water breaks up the molecules". What sort of "physics genious" doesn't even understand how BOILING works?
my point was that you dont have to worry about a leak in the water system... if it does leak its not that big of a deal... any water cooling system that is made today should not leak at all... there is very little pressure and the parts are made of good material so rjust becuase there is water involved doesn't mean people should stay away...
unzip; strip; touch; finger; mount; fsck; more; yes; unmount; sleep
Sorry... either he's lying, or the ducks died from something else randomly. Ducks don't rely on surface tension, they have natural bouyancy which is far greater in force than surface tension. In fact, removing surface tension would make it easier for them to swim, as since they break the surface of the water when swimming surface tension slows them down...
You obviously didn't read (or understand) the link you yourself provided to Red Line's webpage. No, this is not a replacement for glycol anti-freeze. Yes, you should just add it to the water. Pure water conducts heat a *lot* better than water+antifreeze. The best hot-day racing coolant is pure water and a bottle of this stuff. So long as your system is running well, you can't possibly overheat. First-hand experience talking, here.
Instead of water use corn mash! Operate a little distillery from your PC!

But I just can't let myself have running water that close to my components. I'll take obnoxiously loud fans any day (i.e. my dual 120mm Deltas) over the thought of running water being millimeters away from my beautiful hardware.
